求助：614V6 JTAG 失败！

lvluwen

使用使用BRJTAG1.8清除614V6的NVRAM时出现以下错误，何故？貌似不认FLASH，该怎么去改善？

/fc:xx指定。。。再刷就好。。

lvluwen

路由是8M  32M的，FLASH芯片是MX29LV640TTC-90的，

小弟指定了/fc:98 ............. EON EN29LV640T  4Mx16 TopB (8MB)



还是不行啊！

这样弄，开机，等1-2秒，再JTAG。。不要一直插电。。。

xgg54321

或者换个JTAG版本，这个通常刷不死的。。

超级郁闷了，换了几个版本的软件，仍旧提示如下，难道我运气如此只好，超出了通常的范围？
